Ancient Iberia: Peoples and Cultures Before Rome
Before Roman Lusitania
Long before Portugal existed, the western Iberian Peninsula was home to many communities connected by rivers, uplands, Atlantic routes and Mediterranean trade.
Modern labels such as Portuguese and Spanish do not apply to this period. Ancient writers used broad and sometimes inconsistent names, while archaeology reveals local societies that changed over centuries. This guide focuses on the territory that later became Portugal without treating it as an ancient nation.
Prehistoric foundations
- Neolithic period
Farming communities
Agriculture, animal husbandry and permanent settlement expanded, while communities built megalithic tombs and ritual landscapes.
- Copper and Bronze Ages
Fortified centers and metallurgy
Mining, metalworking and long-distance exchange supported increasingly complex settlements and social distinctions.
- Late Bronze Age
Atlantic connections
Metal objects, technologies and cultural practices circulated along Atlantic and inland routes.
- Early Iron Age
New trade networks
Phoenician and other Mediterranean merchants intensified exchange along southern and western coasts.
Who were the Iberians?
“Iberian” can refer broadly to inhabitants of the Iberian Peninsula, but historians also use “Iberians” more specifically for communities in eastern and southern areas with distinctive languages and material culture. In western Iberia, ancient sources mention Lusitanians, Gallaeci, Celtici, Cynetes or Conii and other groups.
Lusitanians
Associated mainly with central western Iberia, the Lusitanians became famous in Roman accounts for resistance led by Viriatus. Their language and social organization remain subjects of research.
Gallaeci
Communities in the northwest lived in a landscape of fortified hill settlements known as castros. Roman administration later organized the broader region as Gallaecia.
Celtici and other groups
Classical authors used Celtic-related names for some interior and southern communities. These labels do not imply a single unified “Celtic nation.”
Southern communities
The Algarve and Alentejo interacted closely with Tartessian, Phoenician and later Carthaginian commercial networks. Writing and imported goods appeared in some areas.
Mediterranean and Atlantic exchange
The peninsula was not isolated. Metals, salt, agricultural products, ceramics, ornaments and technologies moved between inland communities and coastal trading points. Phoenician merchants established settlements and exchange networks in southern Iberia from the early first millennium BCE. Greek goods also reached the peninsula, sometimes through intermediaries.
Atlantic routes linked western Iberia with Galicia, Brittany, the British Isles and other coastal zones. Exchange did not simply bring imported objects; it influenced local production, status, warfare, ritual and settlement patterns.
Hillforts, farms and local economies
Castros
Fortified hilltop or elevated settlements were especially common in the northwest. Stone houses, walls and strategic locations reveal organized communities rather than temporary camps.
River valleys
The Douro, Mondego, Tagus and Guadiana corridors supported agriculture, movement and contact among coast, interior and neighboring regions.
Mining and metals
Gold, copper, tin and other resources attracted trade and later imperial interest. Mining knowledge developed long before Roman conquest.
Pastoral and farming life
Grain, livestock, hunting, fishing and gathering supported diverse local economies adapted to mountains, plains and coastlines.
Rome enters western Iberia
Roman involvement deepened during the Second Punic War beginning in the late third century BCE. Expansion westward was gradual and met repeated resistance. Roman authors often described opponents through the political needs and stereotypes of conquest, so their accounts must be compared with archaeology.
By the late first century BCE, Roman control was established across the territory. Provincial organization, roads, taxation, cities, military recruitment and Latin reshaped society, but local traditions did not disappear overnight.
Ancient and prehistoric places in Portugal
Almendres Cromlech
Near Évora, one of the Iberian Peninsula’s major megalithic complexes helps visitors understand the depth of prehistoric settlement in the Alentejo.
Citânia de Briteiros
A large fortified settlement near Guimarães illustrates northwest Iberian castro culture and later Roman influence.
Cividade de Terroso
Near Póvoa de Varzim, this excavated hill settlement preserves evidence of Iron Age community life and defensive organization.
Mértola and the Guadiana
The strategic river setting shows how inland and Mediterranean networks connected across many historical periods.
Ancient Iberia questions
Were the Iberians the first Portuguese?
No. Portugal did not exist, and ancient communities did not share a modern Portuguese national identity. They are part of the long human history of the territory.
Were all pre-Roman people Celts?
No. Western Iberia contained multiple communities with different languages and cultural connections. Some had Celtic linguistic or material influences, but a single label is misleading.
Did Phoenicians settle in Portugal?
Phoenician trade and settlement influenced southern and coastal Iberia, and archaeological evidence shows strong contacts in areas that are now Portugal.
How do historians know about these peoples?
Knowledge comes from archaeology, inscriptions, linguistics, environmental evidence and Greek and Roman texts, each with limits and biases.
